I have a TT with a monochrome monitor (a Sigma Designs
"Laserview" LDM-0019).  It is physically identical to a
third-party monitor that was sold for the TT, but I cannot
remember the brand name it was sold under in the Atari world.

I had to build a cable, using a DB-9 serial cable and a DB-15
connector for the TT video output.  The wiring is as follows:

pinout for db9 -> db15 cable for ECL monochrome monitor
to Atari TT

   DB9         DB15

    1    ->    4
    2    ->    none
    3    ->    none
    4    ->    none
    5    ->    13
    6    ->    15
    7    ->    none
    8    ->    10
    9    ->    14

  2 & 3      9 & 10
 shorted     shorted

Of course I make no garantee that this will work for you.  But I
would be surprised if the cable pinout was different from one
TT-compatible monitor to the next.  (Someone please correct me
if I am wrong).

Hope this helps.
